of the feeler being-no longer supported down from its higher position into thehanging position, as is illustrated in Fig. 3 for the middle feeler, and the rear limb o of the feeler obviously performs the same turn- 1 3 ing down movement, andthereby directs the thread supplied to the draw-in roller toward one side of the same.

The thread draw-in roller 2) is provided" at its side edge toward which the thread-is deviated on breakage, in the manner shown in Fig. 5 with two obliquely directed catchown account without in any way hindering the turning of the roller 6. p

- If as already stated there occurs a breakage .of the thread and the thread passing to the draw-in roller 7) isldeviated by the feeler 6, then it comes-Within the range of one of the slots of the still rotating roller band is caught by this latter, and receives through the further rotary movement of the draw-in roller a forward pull, while the thread is held fast atthe' draw-in place 0 andis, thereby further drawn, so that the thread must break attheguidepin 0 and thereby'the further delivery of-thread on the supply side is interrupted. The portion of thread falling sidewise fromithe roller (2 cannot tangle itself because it comes to rest on the stationary'protecting diskg. :7 I

. In order to insure uponthe re-insertion inits bearings of the draw-in roller 7) after 1 it has been taken out, "that the tangle protecting disk 9 has its correct position, this latter isprovided at one. point of its perlpherywith a weight 70 (see Figs. 4 and 5) by means of which the disk will always turn automatically into such a position'thatthe i the feeler 6 would hang down with its limbs.

sto n'is located vertically above the bush is: I n the stopping ofthe machine which 1nvolves theceasingof the thread tension 1 In order tonphold the feeler in the operative position even when themachine isnot working a supporting rod 7- is provided withfingers s,'which rod can be so displaced thatthe fingerss engage under the limb e of the feeler and thereby hold fast the'feeler e in .itsi'controlling position.

The construction and the support of each separate feeler e is illustrated best in Figs.

(S and 7. "The socket part of the wire loop 1' forming the. feeler 'is inserted ina metal tube t which passes through the-bearing mvbe'tween the respective thread draw-in rollers b,- and which is-narrowed at its ends q er i lf si ei i ss;in, w h the feeler i'sheld so as to turn easily. The front feeler limb e possesses-at its free end an eyelet ffor the passage of the thread and. the rear liinb e possessesa-turned-in claw.

The two catching. slots, on the thread draw-in roller?) form a. catching or seizing device, ibut,.the sameeifect could also be .ob-

"tained by means of a single catching slot, or;. more than two slots might be provided on the roller. Moreover instead of them a catching device of any other kind might be arranged on the thread draw-in roller or be connected thereto to rotate' withit. -What I claimis:

thread feedstopping device for spinning, twisting and'similar machines, of the kind above referred to, characterized by the combinationzwith a rotatine," thread draw-in roller of a movable'feeler forlaterally deviating the thread on breakage,- guide means for the threadon thesupply side of the draw-inroller and seizing means arranged to -revolve with the draw-in roller and-to seize-the laterally deviated thread,

so as to exert during; further rotation of,

the draw-in irollerfisuch a pull upon the thread onthe supply 1 side that the'thread will necessarily. be broken on said side and thereby the further 'supplyof thread will be interrupted.

2. A- thread feed stopping.device for spinning, twisting and" similar'machines. of the kindfabove referred to, characterized by the combination with a rotating thread draw-in roller of a movablefeeler for laterally deviating the thread onbreakage; guide means for the' thread on the supply side ofthe draw-in roller and 'a catching slot arranged at'that side iedge of saidyroller to which :the'brokenthread is deviated, so 1 as to catch and forcibly break the laterally deviated thread on the supply side upon further rotation of thedraw-in roller, substan'tiallyas described:

3. A thread feedstopping device for spinning, twisting and similar machines, of the kind above: referred to," characterized by thecombination with a=rotatingthread draw-in-rol'ler'of a movable feeler for later ally deviating ithe thread on? breakage; guide means forthe thread on the supp'ly side of the "draw-in roller, seizing-means ariranged to revolve with f the draw-in roller and to seize and fQrciblybreak-thelaterally deviated thread on the 'supply side upon further rotation of the draw-infroller, and anormally stationary tangle protecting disk placed onthat side of the draw-in roller to which the broken thread 'isi deviated; substantiall-y as described.

'4. A thread feed" stoppingf device "for spinningftwisting and similar"; machines; of l the kind above} referred to, i characterized bythe oombinationfa' rotating-thread; 130

draw-in roller of a movable feeler for laterally deviating the thread'on breakage, guide means for the thread on the supply side of the draw-in roller, seizing means arranged 1o protecting disk placed on that side of the tall draw-in roller to which the broken thread is deviated, substantially as described.

In Witness whereof I have hereunto signed my name this 12th day of July 1917, in the presence of two subscribing Witnesses.
